[Infective endocarditis with bivalvular involvement due to Erysipelothrix rhusiopathiae. Report of one case]. / Endocarditis infecciosa con compromiso bivalvular por Erysipelothrix rhusiopathiae.

ABSTRACT

The microbiology of infective endocarditis (IE) varies in different populations and depends on public health conditions and socioeconomic status. In low-income countries, oral Streptococci affect hearts with rheumatic valve disease in patients with poor dentition. In high-income countries, Staphylococci are the most common cause, affecting elderly and immunocompromised patients, or those with invasive devices. Gram - positive bacili as IE pathogens are unusual. Erysipelothrix rhusiopathiae is a Gram positive bacili. It causes skin diseases in domestic and farm animals, but in humans, is a very unusual pathogen. This infection is considered a zoonosis, since most cases are linked to direct contact with vector animals. We report a 62 year-old male patient with a history of exposure to animals, who developed an infective endocarditis with severe bivalve regurgitation and septic shock, requiring antimicrobials and surgical resolution. Erysipelothrix rhusiopathiae was isolated from blood and valve vegetation cultures. The patient had a successful evolution and was discharged from the hospital.
